Vanillic Acid

Product Description

Vanillic Acid is a multi-functional phenolic acid that serves as a key tool for modern cosmetic preservation. Its primary value lies in its potent antimicrobial activity, particularly against yeasts and molds, making it an exceptional preservative booster in a wide range of formulas. As the industry moves away from traditional preservatives, Vanillic Acid allows formulators to significantly enhance the efficacy of alternative preservation systems, helping to create safe and stable "preservative-free" products that meet clean beauty standards. In addition to its preservation-enhancing role, it also contributes valuable antioxidant and anti-inflammatory properties, supporting the overall health and protection of the skin. For formulators seeking to improve the robustness of their preservation systems, our high-purity Vanillic Acid is a reliable and effective solution.

Product Uses

• Preservation Systems: A key component in alternative or "preservative-free" systems (hurdle technology), often used in combination with other multifunctional ingredients like glycols to protect a wide range of formulations.
• Skincare: Used in creams, lotions, and serums, especially in natural or 'clean' product lines, to enhance product integrity and provide secondary antioxidant and soothing benefits.
• Scalp & Hair Care: Incorporated into scalp treatments, conditioners, and shampoos to help control microbial growth and provide soothing properties.

Formulation Suggestions

Recommended dosage: 0.1% - 0.5% when used as a preservative booster.
Vanillic Acid's limited water solubility requires it to be pre-dissolved in a suitable solvent like Propanediol, Pentylene Glycol, or Ethanol before being added to your formula, typically during the cool-down phase. It works synergistically with other ingredients that possess antimicrobial properties, such as Caprylyl Glycol or Phenethyl Alcohol, to create a broad-spectrum preservation effect. It is effective across a moderately acidic to neutral pH range (typically 4.5-6.5), making it versatile for many skincare applications.
